Hydrogen energy storage for a permanent magnet wind turbine generator based autonomous hybrid power system
The Performance of a novel hybrid Remote Area Power Supply (RAPS) system consisting of a Permanent Magnet Synchronous Generator (PMSG), fuel cell system, electrolyser and synchronous condenser is investigated in this paper. The fuel cell system is used to provide power during under-generation scenarios whereas the electrolyser absorbs excess power during over-generation conditions. A synchronous condenser is incorporated into the RAPS system to provide better reactive power and inertial support. Individual controllers for each system module have been developed and implemented. A control coordination methodology is established with a view to regulate the active and reactive power balance of the RAPS system while extracting maximum power from wind for optimal operation of the RAPS system. The entire system was modelled using SimpowerSystem block set in MATLAB and through simulation studies, it has been demonstrated that the proposed RAPS system is able to regulate the voltage and frequency within acceptable limits throughout its operation even during wind speed and load changes.
